There are two hoses that attach to the petcock. One is the fuel supply and the other is the vacuum, both attach to nipples on the carbs. There is a 3rd hose that that attaches to a spot under the fuel tank just in front of the petcock but I don't know where that hose should end up. Is it a drain? Is it a vent? I'll try to post some pics soon. I haven't been in a position to work on the bike and I'll need to take the tank off again.

I did, but maybe I didn't let it turn over enough to circulate the fuel.

I bought this bike at the end of last summer, it was mostly running well but had a few other electrical issues and had just started dripping a little gas from the air intake of the far right (#4?) carb. I took the tank off to sort the wiring and I replaced the petcock vacuum hose that I thought might have been the cause of the leaking fuel. When I put everything back together it cranks but won't start (choke in or out). I suspect it's not getting fuel. It's not dripping fuel now though. I'm wondering about the hose that attaches to the tank at the nipple in front of the petcock. Is that the tank vent? Does it attach to the carb somewhere? I'm 99% sure I have the fuel & vacuum hoses attached in the right place. I have a shop manual and looked online but can't seem to find info showing exactly where that hose is supposed to go. Thanks in advance for any suggestions! PFA

I assume you mean plates to relocate calipers?

I recently got a 1980 GS750E that has been refreshed, painted, etc. I was thinking it would be cool to add more modern, maybe 18" wheels. Are there any (such as late '80s Katana wheels) that would fit the stock frame & forks without modification? I searched the forum for an answer but no luck.
